I work at Arts&Ideas Sudbury School in Baltimore, 8 years old at this point. I have been with them for two years. There is no veto. There is simply discussing the issue and revisiting it if necessary. While it is always possible that a

This seems to be a very enjoyable read. Even if you just skim the equations, it has a really nice perspective on building up relativity and some alternative pathways. Funny enough, I had just gotten to the chapter on Schrödinger's deri

Nature and Growth of Mathematics by Edna Kramer is a fantastic book interweaving history and math.

Yes, practical separation occurs. But you still have to explain why our experience is that of a single outcome when the only thing in the theory (the wave function) says nothing of the kind. Now, this can be rectified by using many worlds,

It is far easier for someone who has been free and living life with eyes wide open to understand and play the game if they choose than it is for someone who has lived a life under authority to suddenly have tremendous freedom. This is why m

For school, it is illegal not to attend. This means in America that people with guns can forcibly detain children not in school during the school day. Police proudly do so in an attempt to defeat crime since, in their opinion, all children

As often presented, QM asserts that the system collapses under measurement. But for a fundamental theory, measurement as an external thing doesn't make sense. Thus, when does collapse happen? This is that cat thing. One can shrug and s

That's sad and is the whole point of treating children with respect as human beings instead of machines that need programming to fulfill the function designated to them by their creators.

As counterpoint, A Thousand Rivers goes the opposite way: http://schoolingtheworld.org/a-thousand-rivers/ I also find it interesting that Larry Sanger's latest post is about the loss of democracy and freedom in t

I have tutored in private schools (rich, not religious) and have heard of how they structure their day. One prominent thing is that of more freedom. They have more time in between classes, more freedom to socialize, and more choice in their

If you find this interesting, I recommend the digital antiquarian: http://www.filfre.net/ I look forward to his post each week. They are detailed, conversational, historical, and insightful. His series on Trinity was simpl

There is a focus in the article in playing outside which is good and fine. But another important aspect missing today is age mixing. This is crucial because it is an informal mentoring process, in effect. 4 year olds learn best from being a

I work for a Sudbury School (Arts&Ideas in Baltimore) where this is our mantra. I've long take it as an article of faith that humans are wired this way. But I am astounded by the comment about artificial intelligence. Is there any

Did you write it as a single file that breaks up into multiple files or was each separate file corresponding to a separate literate document? My tool takes the approach of more of a literate-project approach where one file may generate mult

Interesting that you tried to imitate CWEB to some extent. I wrote my own tool (literate-programming on npm) ignoring very much the syntax of these other tools. My thought is that one reason Knuth's literate-programming did not catch o

1) It ain't dead yet. 2) Tooling/syntax is a big part of it. I like literate programming, but most syntaxes for it turn me off. Some of it also seems very tied to particular languages. None of that helped for a concept that was al

The manager of a group can add emails of people without google accounts. They then only get emails (no web interface meaning no searching) and they cannot change the settings from digest to individual though the manager can. A wee bit unfri

My version of literate-programming may have a bit too much possibility of that magic. I agree it can be dangerous and is something that takes good discipline, like any programming technique. But at least there is something to fall back on i

One functional feature that is missing is that of having blocks in different order. Jeremy Ashkenas argues that because of functions, we do not need that reordering. I disagree with that. I do think a large part of what makes literate progr

As a mathematician, as someone who teaches K-14 math to math-phobic adults in a semester, and as a staff member at a Sudbury school, my biased, anecdotal answer is that mathematical education is designed to tell most students that they can&

I said around children, not having children. The two are completely disjoint. I know lots of people who have children but are not actually around them and are miserable. Conversely, I know people without children who are surrounded by the h

My view is that kids are exploring and loving the world. Adults are support mechanisms for kids (and elderly). But we have been stripped of community and if you happen to not have kids, you can be even more isolated. Being around (free) kid

It depends. There is value to having a progression of one's understanding and ideas and this is ideal for a blog. It can be technical or not. Obviously a post for the ages that one wants to craft over time and update should be its own

The problem is less about when someone learns math (an easy subject once one cares), but rather the attitude about math. In the US, people walk away from math education hating and fearing math. "Math is important, but I can't do m

It is said elsewhere, but the title is very objectionable. If anything, Sudbury schools care more about rules because they are meaningful rules that are created by the community to keep the community functioning smoothly. One can say it is

It is not a long-term babysitting service. It is a community for children to live life, learning the lessons that are needed. As for curriculums, how to get around it depends on the state. Some have no restrictions on private schools. For s

Probably. But the kid would socialize while doing so, learn the skills of mastery, and basically learn how to manage their time in a fulfilling way. Kids at Sudbury schools often do spend a great deal of time on the computers, but that is r

Can you elaborate on what you found difficult as you went to college? How long did it take you to be comfortable with it? And what did you end up studying?
